restricting tekton.dev labels in metadata #2891

pritidesai · 2020-07-02T22:37:24Z

Changes

Tekton resources are automatically assigned certain labels including the ones with tekton.dev. The labels are created and propagated from one resource to another using this group name. We should restrict possibility of overwriting those labels otherwise it could result in conflicting resources.

Result of the discussion in PR 2826

On hold until we confirm this is something we want to restrict 🤔

This will break folks using these labels in metadata, see an example in catalog.

Interesting, those catalog task shouldn't use that label anyway as it is supposed to be set by the controller 🤔

Yup, indeed, @bobcatfish @sbwsg WDYT?

dlorenc · 2020-07-15T22:36:27Z

Yup, indeed, @bobcatfish @sbwsg WDYT?

Ref #2946 - we should probably document this there too

dlorenc · 2020-07-15T22:41:45Z

Yup, indeed, @bobcatfish @sbwsg WDYT?

Is it actually "used" there? The catalog reorg happened so I had to hunt them down (the links changed). Here it is now: https://github.com/tektoncd/catalog/blob/d7e5c6db536d79bd3c205caaf075a50f5c9dee7e/task/github-close-issue/0.1/README.md

They only really appear in the READMEs for examples on creating a TaskRun. My wild guess is that someone created the taskrun with the CLI or something, then dumped it as YAML to generate the docs and kept that label.

It's only in 3 places:

dlorenc · 2020-07-15T22:42:22Z

pkg/apis/validate/metadata.go

+
+	// metadata must not contain any label with tekton.dev/*
+	for k := range meta.GetLabels() {
+		if strings.HasPrefix(k, pipeline.GroupName) {


Do we care/have an opinion on things like "*.tekton.dev" as well?

This is meant to be Tekton internal, created and utilized by the pipeline controller itself, better to enforce rather than relying on Task/Pipeline/TaskRun/PipelineRun authors to follow recommendations, thoughts?

@dlorenc good point. I would think we should reserve tekton.dev and most likely pipelines.tekton.dev (future-proof 😅 ), but given some proposals, we shouldn't restrict all the *.tekton.dev 🙃

+1 on saving the extra namespace. In chains right now we're using "chains.tekton.dev", but only in an annotation.

This PR is restricting labels, annotations have all the freedom 😉

+				Message: "Invalid label key: can not change tekton resource name",


NIT: the error message may be confusing if someone is not trying to change the resource name. I think it would be better to say that the tekton.dev/ labels are reserved for internal use.

afrittoli · 2020-09-24T07:00:37Z

We do use tekton.dev labels in plumbing, so I need to change those before we install this :)

afrittoli

Thanks for this!
I would update the error message, but otherwise it looks good to me.
I think we can reserve extra namespace in further PRs if we decide to?
@pritidesai is the "hold" still needed on this one?

pritidesai · 2020-09-25T15:56:47Z

thanks. Nope, no more hold needed.

Could this be causing integration failure? 🤔 Integration tests failure is consistent with these changes in terms of number of failing Tests:

162 failed / 9 succeeded

pritidesai · 2020-09-25T18:04:25Z

16 test examples showing this error:

TestExamples/v1alpha1/pipelineruns/conditional-pipelinerun-with-same-condition-refer: examples_test.go:57: Failed waiting for pipeline run done: timed out waiting for the condition

pritidesai · 2020-09-25T19:38:17Z

This is actually a legit failure 😢 not related to infra or timeout.

Taskrun and Pipelinerun controller injects these labels which are then going through the same validation routine which validates user specified labels. Will update this PR to separate this validation calls next week, putting it on hold until then.
